Abstract
Six new bis-thiosemicarbazones ligands were synthesized with rigid or flexible organic
links between the two thiosemaicarbazones moieties. Such ligands have been designed for the
synthesis of polymetallic coordination complexes. They were synthesized by the condensation
reaction between aldehydes and substituted thiosemicarbazides in alcohol, using acetic acid
as a catalyst. To determine the structure, composition and purity, the products were characterized
using nuclear magnetic resonance spectoscopy, mass spectroscopy and elemental analysis.
